b Bonnet Vent Relief Outlet Line
For Open systems (Racks, Wallmounts, VMPs, etc.) containing silane:
The
Bonnet Vent Outlet must be kept open to allow gas to escape. It must not be sealed
or routed into other vent lines. It may be covered with a loose fitting cap to prevent
water intrusion provided that it does not prevent gas from escaping. If the standard
outlet location is directed in an unsafe manner (i.e. towards flammable construction
materials, personnel walkways, etc.) or presents another potentially unsafe situation
the outlet must be rerouted to a safe location during installation. Gas detectors
and/or UV/IR detectors should be used in the surrounding area to monitor for a
potential leak.
For Enclosed systems (Cabinets, VMBs, etc.) containing silane:
The Bonnet
Vent Outlet must be kept open to allow gas to escape into the exhaust system. It
must not be sealed or routed into other vent lines. Downstream ventilation
dampers must not be designed to fail closed or close on gas detection. The bonnet
vent outlet should be located upstream of the exhaust gas monitor to detect a
potential leak.
